I have a generic ESP01 board from Amazon - at least that's what the seller says it is.

I have hooked it up to my USB board using a external breakout board that allows you to switch mode (UART / Program).

In UART mode I get a serial port (COM10) in Windows and can use the Serial Monitor in Arduino to send it commands. I have left the factory image in the flash so I can check basic functionality before sending it a sketch.

When I send basic AT commands - everything seems to work :

AT
OK
AT+GMR
AT version:1.2.0.0(Jul 1 2016 20:04:45)
SDK version:1.5.4.1(39cb9a32)
v1.0.0
Mar 11 2018 18:27:31
OK

When I try and send a code that is WiFi specific I get an error:
AT+CWLAP="ssid"
ERROR

Passive Scan
AT+CWLAP=,,,1,,
ERROR

Active Scan
AT+CWLAP=,,,0,,
ERROR

Thoughts anyone ?

Much appreciated

the USB adapter can't supply enough current on 3.3 V pin

Sadly it was an even worse noob mistake - the device needed to be in STA mode for that particular command to work.

Read the docs numerous times before spotting the requirement.

Hehehe, well you always learn best when making mistakes and fixing them on your own.
